also...if there is a variable placed outside the brackets this means whatever is on the brackets must be multiplied by that variable..this variable can be represented by a letter too..(but remember if no variable is show, 1 is always understood to be there), for example 5(45 + 35) ....obviously the first thing that should be done is simplify whats in the brackets, then multiply it by the number outside.... 5(45 + 35) 5(80) 400
() - Brackets...the B being the first letter of BODMAS and it basically states that everything in these brackets have something in common. e.g. - 4(3x + 2)...3x+2 is the expression in the brackets and they share in common that they are both to be multiplied by the four outside of the brackets. if these brackets were expanded we wud have 12x +8...another way to look at this is the other way around...is you have 12x+8 you can factorize this by pulling out what both terms in the expression have in common (i.e- 4) and putting the expression into the brackets.
Why not allow our creator, Jesus, to show His love? Make Him your best friend by telling him the things you tell your best friend. When Jesus is part of your everyday life, well you are on top of the world. The best things will happen and the trials will be testing but the best for you will prevail.
That () are called Brackets
ReplyDeletewe can call it a wall which separates numbers
ReplyDeletei agree with weezy they are called brackets
ReplyDeletethey are like containers that hold numbers and seperate them from others.
ReplyDeleteExamples of the use of brackets are
ReplyDeletei.e the expansion
2x^2+3x
x(2x+3)
what is really its purpose, just to seperate numbers?
ReplyDeletelike in the example above are the brackets are used to simplify the eguation?
ReplyDeleteThey are used like weezy said as seperators but can also be used to group numbers
ReplyDeleteBrackets can be used example:(x+y) (x-y)in algebraic expression.
ReplyDeletebrackets are always solved first BODMAS
ReplyDelete() are brackets
ReplyDeletethey are used to separate numbers
brackets, when given a question which contains a pair of brackets, that usually mean to work out or simplify whats between the pair of brackets...
ReplyDeletealso...if there is a variable placed outside the brackets this means whatever is on the brackets must be multiplied by that variable..this variable can be represented by a letter too..(but remember if no variable is show, 1 is always understood to be there), for example 5(45 + 35) ....obviously the first thing that should be done is simplify whats in the brackets, then multiply it by the number outside....
ReplyDelete5(45 + 35)
5(80)
400

ReplyDeletea bracket or parenthesis as it is known, is used to seperate work and in maths it means multiply
ReplyDeleteBrackets signify that each term outside the bracket must be multiplied by each term inside of the bracket.
ReplyDeleteBrackets can be used to group like terms together. To show belonging.
ReplyDelete2 (3 + 7)
ReplyDeleteDemonstrates that the two must be multiplied by each number in the bracket.
Brackets seperate one operation from an equation to another
ReplyDeleteBrackets is necessary do avoid operation being mixed up
ReplyDeleteExample
ReplyDelete2(5+3)-3(32-5)
